Abstract
Abstract A stripline transmission line is constructed so that the individual conducting and insulating portions of the stripline are free to move relative to each other. This form of construction permits the stripline to be bent to a very small radius without distortion or degradation of its electrical characteristics.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
73 words
A stripline, including in combination, a pair of bare electrical conductors positioned in parallel relationship, first insulator means slidably positioned between and in direct contact with said conductors, said conductors and said first insulator means being formed of flexible material of substantially equal width forming a rectangular configuration, and second insulator means disposed about said pair of conductors and said first insulator means in a restraining slidable engagement with said pair of conductors.
Claim 2
Dependent Claim
73 words
A stripline, including in combination, a pair of bare electrical conductors positioned in parallel relationship, first insulator means slidably positioned between and in direct contact with said conductors, said conductors and said first insulator means being formed of flexible material of substantially equal width forming a rectangular configuration, and second insulator means disposed about said pair of conductors and said first insulator means in a restraining slidable engagement with said pair of conductors.
Claim 3
Dependent Claim
93 words
The stripline of claim 1 wherein, said second insulator means includes a pair of insulating strips each positioned adjacent and in direct contact with a separate one of said electrical conductors to position each of said electrical conductors between said first insulator means and one of said pair of insulating strips, said pair of insulating strips being in slidable engagement with said electrical conductors, said second insulator means further including cover means surrounding said electrical conductors, said first insulator means and said pair of insulating strips and holding the same in desired relationship.
Claim 4
Dependent Claim
32 words
The stripline of claim 2 wherein, said electrical conductors, said pair of insulating strips and said first insulator means are formed of flexible material of substantially equal width forming a rectangular configuration.
Claim 5
Dependent Claim
20 words
The stripline of claim 3 wherein, said first insulator means and said pair of insulating strips are formed of polytetrafluoroethylene.
